nitriles through a one-pot, three-component Strecker reaction of a carbonyl compound, amine, and acetone cyanohydrin in water has been developed. Reactions proceed very efficiently without any catalyst at room temperature with high chemoselectivity and give, in some cases, the expected α-amino nitrile pure after direct separation from water. The protocol is particularly efficient for both aliphatic and
开发了一种简单、方便、实用的方法,通过羰基化合物、胺和丙酮氰醇在水中的一锅三组分 Strecker 反应合成 α-氨基腈。反应在室温下在没有任何催化剂的情况下非常有效地进行,具有高化学选择性,在某些情况下,直接与水分离后得到预期的纯α-氨基腈。该方案对于脂肪族和芳香族醛以及环酮以及伯胺和仲胺都特别有效。报道了 Strecker 反应对 1,2-二胺获得 1,2-二氨基腈和环状仲胺的不寻常应用。
